Environmental Policy Promotes Development of Ground Source Heat Pump Industry

Abstract: It is understood that the rapid rise in world energy prices and the need for the Chinese economy to maintain a high growth rate must consider environmental protection and sustainable development. Building energy conservation and environmental protection are the focus and focus of China's construction industry in the 21st century. . Ground-source heat pump air-conditioning systems have gradually won the market with the advantages of using renewable energy, being friendly to the environment and having low operating costs.

Ground-source heat pump is an efficient and energy-saving air-conditioning system that utilizes both shallow and underground geothermal resources (also called ground energy, including groundwater, soil, or surface water, etc.) that are both hot and cold and can provide domestic hot water. In general, the source heat pump consumes 1 kW of energy, and the user can obtain more than 4 kW of heat or cold. Compared with the boiler (electricity, fuel) heating system, boiler heating can only be more than 90% of the energy or 70-90% of the internal energy of the fuel for the user, so the ground source heat pump than the electric boiler heating More than two-thirds of the electrical energy saves more than one-half the energy of the fuel boiler. The proposal of the “12th Five-Year Plan” for energy saving and environmental protection is in line with the advantages of ground-source heat pumps and is conducive to the development of ground-source heat pump companies.

Relevant information shows that since 1993, China has become a net importer of petroleum. In 1999, 22% of total oil consumption was imported oil, and oil imports reached 120 million tons. China's total energy consumption has already ranked second in the world, accounting for about 11% of the world's total energy consumption. There is a huge gap between the efficiency of energy use and the international community. The total energy efficiency in China is about 30%. . Com energy saving is about 50-60% of the energy consumption of public buildings in China is consumed in air-conditioning refrigeration and heating systems, 20-30% for lighting.

It is understood that China is a big country in coal production and also a big country in coal consumption. The proportion of coal in disposable energy production and consumption is as high as 72%. . Com New Energy's coal-based energy structure has caused extremely serious atmospheric pollution. Of the ten most polluted cities in the world, China accounts for four. 90% of China's sulfur dioxide emissions and 70% of the dust in the atmosphere are caused by coal combustion. This has caused serious damage to the ecological environment, but also brought us a huge environmental pressure.

With the rapid rise of world energy prices, the Chinese economy must maintain a high growth rate, and environmental protection and sustainable development must be considered. Building energy conservation and environmental protection are the focus and focus of the development of Chinese construction in the 21st century. Ground-source heat pump air-conditioning systems have gradually won the market with the advantages of using renewable energy, being friendly to the environment and having low operating costs. Because of the advantages of ground-source heat pump technology, the industry has developed rapidly in China and has received high attention from the state and strong support from local governments. The market for ground source heat pumps is constantly expanding, and the advantages of ground source heat pumps are becoming increasingly prominent. Ground-source heat pump will promote China's energy-saving and environmental protection economic development.
